A system for managing consumption of power supplied by an electric utility to power consuming devices includes at least one client device and a server. Each client device operates at least partially responsive to control messages received from the server and controls operation of one or more controllable devices. Each controllable device selectively enables and disables a flow of power to one or more of the consuming devices. The server stores information, on a per client device basis, relating to power consumed by the consuming devices. When a power reduction is requested by the utility, the server selects, based on client device information stored in the database, at least one client device to which to issue a power reduction message that indicates at least one of an amount of power to be reduced and an identification of a controllable device to be instructed to disable a flow of power.

A system and method for facilitating welding system diagnostics is provided. The invention includes a welder, a local system, a remote system, and / or an alarm component. The invention further provides for receiving sensor input(s), performing test sequence(s) based, at least in part, upon the sensor input(s) and / or performing internal diagnostics. The invention further provides for determining a health status of the welder and communicating the health status of the welder to the local system, the remote system and / or the alarm component. The health status of the welder can include welder alarm(s) and / or fault(s). Information regarding the health status of the welder can be sent by telephone, voicemail, e-mail and / or beeper. The welder can communicate with the local system and / or remote system to schedule maintenance. The invention further provides for a expert component to facilitate welding diagnostics based, at least in part, upon the health status of the welder, welder data, an expert data store, a local service support data store, a remote expert data store and / or a remote service support data store. The expert component can employ various artificial intelligence technique(s) (e.g., Bayesian model, probability tree network, fuzzy logic and / or neural network) to facilitate welding diagnostics based, at least in part, upon the health status received from the welder. The expert component can adaptively modify its modeling technique(s) based upon historical success (e.g., learn from success of previous welding diagnostics). The invention further provides for the welder, local system and / or remote system to initiate corrective action, at least temporarily, based, at least in part, upon the health status of the welder.

A tape printer, wherein when a label tape (36) is fed to a tape cutting position after the label (39) of the label tape (36) is printed out, the heating elements (R1 to Rn) of a thermal head (9) are disposed so as to be opposed to the position of a next printed label (39) slightly on the upstream side of a label head position on the downstream side of thereof in the feeding direction and to be opposed to the position of the next printed label (39) on the downstream side of the printing start position thereof (so that a<b can be established in FIG. 7), and a mark detection sensor (12)is disposed on the upstream side of the heating elements (R1 to Rn) so as to be opposed to the position slightly on the downstream side of the position opposed to a position detection mark (39B) (so that c<e can be established in FIG. 7).

A method and apparatus for detecting a joint between workpieces is provided. At least one light line is recorded by the light section method to detect the three-dimensional course of the joint and a grey-level image of the joint is also recorded. The grey-level image is evaluated to assess the quality of the joint.

There is provided method for joining dissimilar metals of a steel product and a light metal product with each other, wherein the light metal product and a rivet made of an iron-base metal are connected with each other beforehand in a previous process preceding spot welding, and subsequently, the rivet and the steel product are spot welded with each other. Then, a cavity for use in clinching the light metal product is formed, and upon the stem of the rivet is embedded into the light metal product to penetrate therethrough, light metal is caused to undergo plastic flow into the cavity of the rivet, for clinching the light metal product to be thereby clinched with the rivet whereupon spot welding for forming a weld nugget only within the scope of an interface between the stem of the rivet, and the steel product is carried out. Thus, the present invention can implement the spot welding between iron-iron similar metals, without a constraint on, and a problem with conditions applicable to the spot welding and a high joint strength can be obtained owing to the synergistic effect of the spot welding and connection by clinching of the aluminum alloy product with the iron-base rivet, added thereto.
